That 2.5L was a good first car engine, low on power but simple. They had lots of valvetrain noise but held together well. They improved it in some ways on the 88. My 86 with that engine was only at about 90K when it got in a wreck unfortunately.
I remember once as a teenager I parked my 86 GA near an old guy on a park bench, and he started asking me what was wrong with the engine. That thing practically sounded like a diesel, but typical for them. I always recognized when somebody had an iron duke running nearby. One time I heard one in a Firebird.. up until then I had no idea such a thing was possible.
To me...Iron Duke Equals the mail has arrived, as that is what the Grumman LLV the post office used near me came with.
